Check in was very easy and friendly, with people at the office 24/7. It's worth checking Street View before coming (look beside the Esso on Sutthisan), because the building is set back from Sutthisan Road behind another building - Pia sent us the info in advance to help us find it. Location is very convenient, on a main road less than 10 minutes from skytrain and convenient for taxis to/from both airports, with plenty of options to eat and convenience stores almost next door. But because it's set back away from the road, it's remarkably quiet and peaceful, with a small balcony looking out over greenery. The place is clean and has everything you need, including mini-fridge and water boiler (note coffee is just 3-in-1s, we brought our own). Definitely hoping to stay again next time we're in Bangkok.
